A memorial ?

It would be good to have a simple plaque or better still to have a sculpture of a white ghost bike in memory of all the dead and injured on london roads. It needn't have any names on, otherwise it would have to be constantly updated. Councils may resist such an idea on the grounds that it may become a focal point for protest. This would be easily overcome by finding a sympathetic freeholder with a suitable space near their building. I for one would definatley chip in for the cost. If such a thing exists, please post the address. Cheers.
